Electricity: power supply or regulation systems

SECTION I - CLASS DEFINITION

GENERAL STATEMENT OF CLASS SUBJECT MATTER

1. Class Scope

This is the generic class for electrical systems wherein a single electrical source is coupled to a single electrical load circuit and means are provided which control the magnitude or level of the current or voltage of either or both of said circuits and/or the phase angle between the current or voltage of either or both of said circuits.

This is also the generic class for transformer systems, see TRANSFORMER SYSTEMS below.

This is also the generic class for impedance systems, see IMPEDANCE SYSTEMS, below.

2. Voltage Magnitude and Phase Control Systems

In order to be classified in this class, the system must operate to control only (1) the magnitude of the current or voltage and/or (2) the phase angle between the current and voltage of an electric circuit. Where the system operates to perform some other additional function, classification is not herein. For a partial list of the classes which provide for such excluded systems, see the classes listed in the class definition, under "SEARCH CLASS."
